ETW-E Digital Torque Wrench

ETW-E Series Features

Typical Applications

• A laboratory device for developing fastening specifications for applications
• SPC Quality control and data collection

20 Customer Application Setups

• Store custom fastening strategies for specific applications

Data Storage

• Stores up to 1500 final tightening values per application setup.
• Stores up to ten tightening traces

Four Tightening Modes

• Torque control – For accurate torque tightening
• Torque plus angle control – For Tightening to a specific angle beyond snug Improved clamp load consistency on more critical applications
• Yield control – For tightening to yield point of fastener. For obtaining maximum clamp load from fastener
• Track Mode - For real time torque analysis

Statistical Capability

• SPC calculations including mean, standard deviation, Cp, Cpk, R, Cm, Cmk, and CAM can be viewed on screen.

Direct computer Interface

• Integral RS232 port allows for direct connection of tool to computer for downloading fastening data traces.
• For additional functionality, it can be used in conjunction with the PC Comms software.
• The features of the Expert Wrench significantly enhance the scope of information delivery, as well as accessibility and ease of use:
• Built-in non-contact angle measurement On-board storage of tightening data to eliminate the need for a local PC
• Quality control limits on tightening parameters give an instant picture of the fastening quality and help ensure a “good” tightening
• Serial interface for transmission and analysis of data
• The Expert Wrench is far more capable than operator-dependent hand torque wrenches, and is the perfect supplement to power tools, whether basic or advanced. It enables operators to gain control of fastening operations by setting standards, auditing performance, and monitoring repairs. The Expert Wrench is the only tool of its type that detects the yield point of the fastener. Because problems occur when fasteners are attached without sufficient tightness, the solution focuses on getting bolts as tight as possible…safely.
